ENVELOPE.

Application filed March 13, 1920. Serial No. 365,532.

To all whom it may concern:

Be it known that l, OHAnLns R. WILLIAMS, a citizen of the United States,residing at Omaha, in the county of Douglas and State of Nebraska, haveinvented certain new and useful Improvements in Envelopes, of which thefollowing is a specification.

My invention relates to improvements in envelopes, and the main objectof my invention is the provision of an envelope which will possess adouble seal, and thus prove of greater security and have more lastingqualities than the usual envelopes.

Another object of my invention is the provision of a double sealenvelope which will perform all the functions of the ordinary envelopeand which maybe used as a combined envelope and letter sheet if founddesirable.

Another object of my invention is the provision of an envelope whichwill require little adhesive matter in its production;

which will be strong and durable; and

thoroughly efficient in every respect.

\Vith these objects in view my invention consists of an envelopeembodying novel features of construction and arrangement of its parts asshown, described and claimed herein.

Figure l is a plan View of the complete blank or sheet from which theenvelope is produced, looking at the inner face of the sheet.

Figure 2 is a plan View of the envelope with the parts in the positionthey assume when the four side flaps have been turned in or folded informing the pocket of the envelope, and

Figure 3 is a central vertical sectional view of the completed envelope,the outer sealing flap being open or raised.

In producing my envelope a sheet or blank A is used which is scored atB, to form the main portion A and has at one end the guinmed outersealing flap C, and at its other end the flap D, the gummed flap formingthe outer sealing flap for the envelope, while the flap D, provides whatmay be termed the inner sealing flap.

lhe main portion A is formedwith the two pairs of lateral flaps E and Ewhich are adapted to be folded inward to have their ends F overlap, andform the reinforcing portion G for protecting the pocket ii, formed bythe adjacent overlapped flaps E, the reinforcing portion folding uponthe pocket portion and in use the flap D folds in and seals the pocket,as seen in F igure 3, and the outer sealing flap C, closes the pocketwith the inner seal. Thus an envelope is provided having a double seal,a series of thicknesses of material to make the envelope tough andstrong, and one wherein the only adhesive necessary 1n the making of theenvelope, is that which is used upon the outer sealing flap.

The envelope can be quickly and cheaply 7 made, can be used as acombined writing sheet and envelope, or only as an envelope, can beproduced by an unskilled person and generally is a practical idea.

I claim:

An envelope formed from a single piece of material, said envelopecomprising a rectangular body portion, spaced flaps extending outwardlyfrom one side of said body portion, spaced flaps extending outwardlyfrom the opposite side of the body portion and in alignment with thefirst mentioned fiaps,the flaps at the opposite sides "of the bodyportion being adapted to fold onto each other so that their endswill.overlap thereby forming pockets in combination with the bodymember-after the. body member has been folded on itself ona line inregistration with the spaces between the flaps, an outwardly extendingflap carried by one side of thebody member and dis posed between theflaps and at an angle thereto and adapted to be received inthe pocketformed at the opposite end of the body member, and a gummed securingflap for engaging over the outwardly extending flap and securing to theouter side of the body member adjacent the first mentioned flap.

In testimon whereof I afiix my signature.
